TAKE-DOWN DEVICE.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Application filed November 9, 1914. Serial No. 871,078.

To all whom it may concern:

Be it known that LHARRY E. DE VAUGHN, a citizen of the United States,residing at Morgantown, in the county of Monongalia and State of WestVirginia, have invented new and useful Improvements in Take- DownDevices, of which the following is a specification.

This invention is an apparatus for taking down glass cylinders after thedrawing operation has been completed.

One of the objects of the invention is to provide an apparatus by meansof which the glass cylinder may be engaged while in vertical position,turned to a horizontal position, and be deposited upon a suitable horseor support. A further object is to provide means for shortening the timerequired for the take down operation without jeopardizing the safety ofthe cylinder. A further object is to provide means for cushioning thecylinder and relieving the same of shocks to which it is normallysubjected in the take down process. A further object is to provide anapparatus of this character which does not necessitate the employment ofcounterweights, levers, and the like, now commonly employed with thistype of apparatus.

The invention will be hereinafter fully set forth and particularlypointed out in the claims. I

In the accompanying drawings Figure 1 is a diagrammatic side elevationillustrating my invention. Fig. 2 is an enlarged detail View thereof.Fig. 3 is a sectional view on the line 33 Fig. 2.

Referring to the drawing, 10 designates the stationary frame of thedrawing machine, 11 the cage guided by said frame, 12 the cable leadingto a suitable motor (not shown), for operating said cage, 13 the baitsupported by said cage, and 14 the cylinder as it appears at the end ofthe drawing op eration and ready to be taken down.

A cable 15 is secured at one end as indicated at 15*, to a part of theframe-work of the drawing frame, said point being fixed or stationary.The other end of the cable is connected to a trolley 16 mounted toreciprocate upon tracks 17 resting at one end upon an I-beam 18, theother end being supported by a hanger bar 19. I prefer to interpose aspring 20 between the end of the cable 15 and the trolley 16. Saidtrolley is provided. with suitable carrying wheels 21 which permit ofthe ready movement of the trolley along the track 17. The ends of thetrolley are connected to the ends of a belt 22 passed around suitablepulleys 23 supported by the track 17, and operated by a motor 24 of anypreferred type, and receiving its power from any suitable source.Mounted upon the rope 15 is a trolley 25 provided with carrying wheels26, and a depending supporting yoke 27 which is yieldingly sustained bycoiled springs 28. Depending from the yoke 27 is-a hook 29 which engagesa loop 30 of a hoop 31 passed around the lower end of the cylinder whenthe latter is to be taken down.

In operation, when the cylinder 14 has been drawn to the desired heightand severed at its lower end from the bath of molten glass, the motor 24is operated to move the trolley 16 to the point indicated in Fig. 1.This permits the trolley 25 to be lowered so that the hoop 31 may bepassed over the lower end of the cylinder, and the loop 30 engaged withthe hook 29. As soon as this is done the motor 24 isoperated to thesupport, the trolley 25 traveling along the cable 15. The operator thenreverses the operation of motor 24, thus moving trolley 16 toward thedrawing frame, thereby slackening the cable and allowing the cylinder tomove down gently into the support. By this arrangement the taking downoperation is greatly shortened and the spring 20 serves to relieve thecylinder of shocks to which it is normally subjected in the taking downprocess. The parts are simple in construction and counterweights, leversand the like now commonly employed are rendered unnecessary.

Having thus explained the nature of my invention and described anoperative manner of constructing and using the same, although withoutattempting to set forth all of the forms in which it may be made, or allof the forms of its use, what I claim is 1. An improved take-downmechanism for glass drawing apparatus, comprising a cable having one endsecured to a fixed point, a support for the other end of said cable,said support being movable toward and from said fixed point, means forcontrolling the movement of said movable support, and means mounted onthe cable for supporting the severed end of the cylinder.

2. An improved take-down mechanism for glass drawing apparatus,comprising a cable having one end secured to a fixed point, ahorizontally reciprocable support for the other end of said cable, saidsupport being movable toward and from said fixed point, means forcontrolling the movement of said support, and means mounted on the cablefor supporting the severed end of the cylinder.

3. An improved take-down mechanism for glass drawing apparatus,comprising a cable having one end secured to a fixed point, ahorizontally movable support IP01 the other end of said cable, saidsupport being movable toward and from said fixed point, a motor forcontrolling the movement of said support, and means mounted on the cablefor supporting the severed end of the cylinder.

4:. An improved take-down mechanism for glass drawing apparatus,comprising a cable having one end secured to a fixed point, a supportfor the other end of the cable, said support being movable toward andfrom said fixed point, means for controlling the movement of saidsupport, cushioning means interposed between the cable and said movablesupport, and means mounted on the cable for supporting the severed endof the cylinder.

5. An improved take-down mechanism for glass drawing apparatus,comprising a cable having one end secured to a fixed point, ahorizontally reciprocable support movable toward and from said fixedpoint, means for controlling the movement of said support, a springconnecting said support with the other end of said cable, and meansmounted on the cable for supporting the severed end of the cylinder.

6. An improved take-down mechanism for glass drawing apparatus,comprising a cable having one end secured to a fixed point, a horizontaltrack, a trolley movable on said track toward and from said fixed point,means for operating said trolley, the other end of the cable beingconnected with said trolley, and means mounted on the cable forsupporting the severed end of the cylinder.

7. An improved take-down mechanism for glass drawing apparatus,comprising a cable having one end secured to a fixed point, a horizontaltrack, a trolley movable 011 said track toward and from said fixed pointand connected with the other end of said cable, a motor on said track, abelt operated by said motor and connected with said trolley, and meansmounted on the cable for supporting the severed end of the cylinder.

8. An improved take-down mechanism for glass drawing apparatus,comprising a cable having one end secured to a fixed point, a horizontaltrack, a trolley movable on said track toward and from said fixed point,a spring connecting said trolley with the other end of said cable, meansfor operating said trolley, and means mounted on the cable forsupporting the severed end of the cylinder.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
